Question

Sound produced at a point is heard by a person after 5 second, while the same sound is heard by another person after 6 seconds. If the speed of sound is 300 m/s, what could be the maximum and minimum distances between the two persons?

Answer 1

speed of sound = 300 m/s
distance travelled in 5 second = 300×5 = 1500m
distance travelled in 6 second = 300×6 = 1800m

If they are on opposite side of the source, the distance will be maximum
D = 1500+1800 = 3300m 

If they are on same side of the source, the distance will be minimum
D = 1800-1500 = 300m

So maximum distance is 3300m and minimum distance is 300m.
